Evaluation of different postharvest conditions to preserve the amount of bioactive compounds, physicochemical quality parameters and sensory attributes of ‘Sweetheart’ cherries.

Sweet cherries (Prunus avium L.) ‘Sweetheart’ were harvested at different production regions from Portugal (Cova da Beira and Portalegre) and Spain (Valle de Jerte). Cherries were harvested at their commercial maturation according to the empirical knowledge of external color corresponding to good quality. Fruits were stored and evaluated in order to study their quality on the harvest day and during a period of 21 days, at cold storage (1 ºC, 95% RH). The sweet cherry ‘Sweetheart’ is a well-known variety and a highly appreciated one but fruits present a short shelf life. On the other hand the effect of different “terroir” on cherry characteristics should be known and clarified. Fruits from day 0, considered without storage, were kept at 20ºC and analyzed. Every weak, 3 replicas were randomly picked up and 10 fruits from each one were submitted to several analyses after fruit temperature stabilized at 20ºC. Several quality parameters were evaluated: external colour (L*, a*, b*), texture, soluble solids content (SSC), titratable acidity (TA) and the ratio between soluble solid contents (SSC) and tritratable acidity (TA). Fruits from different orchards and locations were significantly different according to these parameters. Fruits from Cova da Beira were less firm comparing with other two regions, Valle de Jerte and Portalegre, which may indicate a higher maturation rate at harvest in those fruits. This is in accordance with SSC/titratable acidity rate suggesting a late harvest in Cova da Beira comparing with other two orchards, however fruits from Cova da Beira exhibit a poor color at harvest. These results clearly showed a lower correlation between SSC and firmness considering fruits origin.

Os alunos de risco no 2º ciclo da Escola Básica 2, 3 Ana de Castro Osório, no ano lectivo 2004/2005: um estudo de caso

O presente estudo aborda a problemática dos alunos de risco no 2° Ciclo da E.B. 2,3 Ana de Castro Osório, no ano letivo 2004/2005. Na dimensão teórica são referenciadas algumas questões de Organização Escolar (escola reflexiva, autonomia de escola, gestores intermédios e supervisão escolar, o papel do Diretor de Turma, o Projeto Curricular de Escola, algumas linhas orientadoras da política educativa portuguesa, no período em que decorre a elaboração desta investigação) e abordados alguns aspetos gerais dos pré-adolescentes, diversos conceitos de risco, a ação de diversas entidades com competência na área da infância e juventude, o papel da família e a relação desta com a escola. Foi utilizada a metodologia do “Estudo Caso”, no decurso da qual foram analisados documentos internos da escola e elaborados instrumentos de recolha de dados (questionários aplicados aos Alunos e aos seus Diretores de Turma). No tratamento das informações de natureza quantitativa, utilizou-se o programa informático Excel, enquanto nas questões abertas procedeu-se à análise de conteúdo. Em síntese, concluiu-se que: a) um terço dos alunos que frequentava o 2° Ciclo do Ensino Básico, foi sinalizado como “aluno de risco”. Cerca de 75% era do 5° Ano de Escolaridade. Os fatores de risco que mais se destacam são: assiduidade irregular, desmotivação/desinteresse/apatia, défice de atenção e concentração, indisciplina e retenções sucessivas no seu percurso escolar. A família é pouco participativa. b) a resposta curricular dá-se essencialmente dentro da sala de aula; c) a resposta organizacional assenta essencialmente nalgumas medidas previstas nos documentos legislativos. Na última parte do trabalho deixamos expressas as conclusões do estudo mais pormenorizadas, bem como algumas recomendações/sugestões que eventualmente, poderão orientar posteriores investigações. /ABSTRACT - The risk students on a 2nd Cycle of classroom of the E.B. 2, 3 Ana de Castro Osório, during academic year of 2004/2005: A Case study The present study attempts to assess risk students on a 2nd Cycle (Sth and 6th grades) classroom of the “E.B. 2, 3 Ana de Castro Osório” Public School during the academic year of 2004/2005. On a theoretical scale, are assessed some questions about the Classroom Organization (reflexive school, school autonomy, intermediate directors and school supervision, the role of the Class Tutor, the School Curricular Project, some guidelines about the Portuguese education policy during the period when this study took place), and was also assessed some general aspects of preadolescents, risk concepts, and actions taken by various organizations specialized in the areas of childhood and youth, the role of the family and the interrelation between the family and the school. It was used a “Case Study” methodology during which was assessed school documents of this particularly school, and data collecting instruments (Student-applied and Class Tutor-applied questionnaires). On dealing with quantitative data, it was used the Excel application, while for the open questions was assessed by its contents. In brief, it was concluded that: a) a third of students that attended the 2nd Cycle Basic Education schools revealed to be “risk students”. Around 75% of them were 5th grade students. Among the most important risk factors are: irregular attendance, unmotivated/aloofness /apathy, lack of attention and concentration, indiscipline and successive retentions during their education pathway. The family is scarcely participative. b) The curricular response is normally given within the classroom; c) the organizational response lies mostly on some measures included in government documents. On the last part of the paper, we focus on more detailed conclusions, as well as give recommendations/suggestions which may eventually be of guidance to future studies.

Entrevista com Ana Paula Amendoeira

A paisagem cultural foi o tema condutor desta entrevista com Ana Paula Amendoeira, que nos apresenta a sua perspectiva sobre os problemas e os desafios presentes na discussão sobre políticas públicas para a protecção e valorização das paisagens culturais em Portugal. Directora Regional de Cultura do Alentejo desde 2013, Ana Paula Amendoeira é especialista em património histórico e paisagístico. O seu percurso é marcado pela experiência na administração pública local e regional, pela investigação no âmbito da reflexão sobre património mundial e pelo activismo associativo, nomeadamente na Comissão Nacional Portuguesa do Conselho Internacional de Monumentos e Sítios (ICOMOS Portugal). De que falamos quando nos referimos à patrimonialização da paisagem? Que constrangimentos, balanços e desafios futuros? Que contributos dos museus?

A real time Taqman RT-PCR for the detection of rabbit hemorrhagic disease virus 2 (RHDV2)

As key prey, the wild rabbit downsize constitutes a major drawback on the endangered Iberian lynx (Lynx pardinus) re-introduction in the Iberia. Several captive breeding units mostly located in Alentejo, endeavour the wild rabbit repopulation of depleted areas assigned for the lynx re-introduction. Here we report an RHDV2 outbreak that occurred in early 2016 in a wild rabbit captive breeding unit located in Barrancos municipality. The estimated mortality rate between March and April 2016 was approximately 8.67%. Anatomopathologic examination was carried out for 13 victimized rabbits. Molecular characterization was based on the complete vp60 capsid gene. The 13 rabbit carcasses investigated showed typical macroscopic RHD lesions testing positive to RHDV2- RNA. Comparison of the vp60 nucleotide sequences obtained from two specimens with others publically available disclosed similarities below 98.22% with RHDV2 strains originated in the Iberia and Azores and revealed that the two identical strains from Barrancos-2016 contain six unique single synonymous nucleotide polymorphisms. In the phylogenetic analysis performed, the Barrancos-2016 strains clustered apart from other known strains, meaning they may represent new evolutionary RHDV2 lineages. No clear epidemiological link could be traced for this outbreak where the mortalities were lower compared with previous years. Yet, network analysis suggested a possible connection between the missing intermediates from which the strains from Barrancos 2013, 2014 and 2016 have derived. It is therefore possible that RHDV2 has circulated endemically in the region since 2012, with periodic epizootic occurrences. Still, six years after its emergence in wild rabbits, RHDV2 continues to pose difficulties to the establishment of natural wild rabbit populations that are crucial for the self-sustainability of the local ecosystems.

Mulheres Escultoras em Portugal

Como qualquer outra expressão artística, a Escultura tem especificidades singulares que fazem desta actividade um desafio técnico de vulto. Em tempos passados as condições técnicas e o agir artístico que a Escultura exigia e exige não permitiam, como no caso do Desenho e da Pintura, que fosse com a mesma facilidade e frequência uma prenda feminina que lustrava os grupos sociais economicamente favorecidos. Os actos e gestos que exigiam força, eram vistos como algo demasiadamente másculo e o atelier de escultura considerado um lugar impróprio. Seguir esta actividade tornava uma mulher extremamente invulgar, mais rara ainda que as pintoras, constituindo-se como uma afirmação de personalidade.Este livro aborda um conjunto de escultoras pouco conhecidas, ou mesmo desconhecidas e algumas que alcançaram ampla visibilidade.Praticamente todos os nomes abordados foram registados como palavras-chave.Esperamos que estes estudos de caso contribuam para um panorama mais completo do nosso património artístico e que mais tarde possam integrar uma História da Arte que contemple lado a lado escultores e escultoras.
